Abstract: Experimental and theoretical investigations were made of the influence of external thermal effects on the dispersive characteristics of single-mode fiber waveguides with different shapes and parameters of the refractive index profile. The temperature coefficients of the group delay were determined. The temperature dependences of the dispersion coefficient ($dD / dT= 1.6\times 10^{-3}$ and $4.3\times 10^{-3}$ ps$\cdot$nm$^{-1}$ km$^{-1}$ K$^{-1}$, respectively) and of the zero-dispersion wavelength $(d\lambda_0 / dT = 1.9\times 10^{-2}$ and $8.5\times 10^{-2}$ nm$/$K, respectively) were determined at two working wavelengths of 1.3 and 1.55 $\mu$m for single-mode fiber waveguides with typical parameters.
